I just bought this car, it is in beautiful.

Chromed steel? Plastic? Painted? What's wrong with them? Bent? Peeling paint? Torn?

For steel bumpers, do a search for "bumper repair" and look for "Bumper Boyz".

For plastic, visit a body shop. They have ways of repairing plastic but it is usually less expensive to replace them. They have special additives for the paint to make it stay flexible. Those are considered bumper covers.
